Steve is a gorilla who lives at a zoo in Rio. In the evenings, he listens to jazz on the radio with his friend, Antonio the zookeeper. One night, Steve is feeling a little lonely and so he lifts the latch of his cage door and goes off to search for Antonio. At the tram stop outside the zoo, he finds a hat — the perfect disguise. Steve climbs aboard a tram and rides down the hillside, past the favelas and into the city. It is carnival time in Rio! Fireworks explode in the sky and sequinned dancers shimmy along the avenue.
‘Feliz Carnaval’ cry the sambistas. Steve follows the sounds of a saxophone and discovers his friend Antonio playing in a quartet at the Blue Jaguar Jazz Club. When a beautiful dancer steps on to the dance floor, Steve takes her by the hand. They twirl and twist to the music until suddenly, Steve’s hat falls off to reveal he is a gorilla! Calmly, the dancer puts Steve’s hat back on his head and they spin this way and that way, this way and that way, all the way to dawn.
